When the humans have been chased from the farm, what do the animals do ?

From the Text:

"For the first few minutes the animals could hardly believe in their good fortune. Their first act was to gallop in a body right round the boundaries of the farm, as though to make quite sure that no human being was hiding anywhere upon it; then they raced back to the farm buildings to wipe out the last traces of Jones's hated reign. The harness-room at the end of the stables was broken open; the bits, the nose-rings, the dog-chains, the cruel knives with which Mr. Jones had been used to castrate the pigs and lambs, were all flung down the well. The reins, the halters, the blinkers, the degrading nosebags, were thrown on to the rubbish fire which was burning in the yard. So were the whips. All the animals capered with joy when they saw the whips going up in flames. Snowball also threw on to the fire the ribbons with which the horses' manes and tails had usually been decorated on market days."

The next morning....

"......they woke at dawn as usual, and suddenly remembering the glorious thing that had happened, they all raced out into the pasture together. A little way down the pasture there was a knoll that commanded a view of most of the farm. The animals rushed to the top of it and gazed round them in the clear morning light. Yes, it was theirs–everything that they could see was theirs! In the ecstasy of that thought they gambolled round and round, they hurled themselves into the air in great leaps of excitement. They rolled in the dew, they cropped mouthfuls of the sweet summer grass, they kicked up clods of the black earth and snuffed its rich scent. Then they made a tour of inspection of the whole farm and surveyed with speechless admiration the ploughland, the hayfield, the orchard, the pool, the spinney. It was as though they had never seen these things before, and even now they could hardly believe that it was all their own."
